Has Blake Lively Already Found Leo's Replacement?

Earlier today, reps for Blake Lively and Leonardo DiCaprio confirmed the couple split ... but the "Gossip Girl" star may not be sitting at home crying about it.

According to the Boston Herald, she's been spotted in Beantown with her "Green Lantern" co-star Ryan Reynolds!

The two were reportedly seen catching a Radiohead show together in NYC (with Ryan's ex-wife Scarlett Johansson, no less) before hopping on a train to Boston, where Reynolds has been filming an upcoming flick.

Reynolds and Blake, who have been the topic of hookup rumors before, were also seen grabbing a bite at O Ya Sushi over the weekend.

We still want to see some photos before fully believing it, but they would make one sexy couple.
